BACKGROUND ART

In the related art, there is known a mounting device which mounts alight emitting component, which is provided with an illuminant such asan LED, onto a board. There is known a mounting device which accuratelypositions a light emitting center of the illuminant on the board even ina case in which the positional accuracy of the illuminant in the lightemitting component is poor. For example, a bonding device described inPTL 1 first captures an image in a state in which the light emittingcomponent is caused to emit light, and calculates relative coordinatesbetween the light emitting center and an outer shape reference point ofthe light emitting component based on the image. Next, the device imagesthe light emitting component in a state in which the light emittingcomponent is held by holding means, and recognizes the outer shapereference point of the light emitting component based on the capturedimage. The device calculates the position of the light emitting centerbased on the outer shape reference point which is recognized and therelative coordinates which are calculated, and in a case in which apositional deviation amount between the position and a bonding positionis great, the bonding position is corrected, and the light emittingcomponent is bonded onto the board.

SUMMARY

As described above, in PTL 1, it is necessary to calculate the relativecoordinates between the light emitting center and the outer shapereference point of the light emitting component based on the capturedimage in order to accurately position the light emitting center on theboard. However, due to reasons such as the visual field of imaging meansbeing narrow, for example, there is a case in which the illuminant andthe outer shape reference point of the light emitting component may notbe imaged as a single image. In this case, the relative coordinatesbetween the light emitting center and the outer shape reference pointmay not be calculated from the image, and the method described in PTL 1may not be used.

The present disclosure is made in light of this problem, and the mainobject of the present disclosure is to accurately position an illuminanton a board without using information relating to the outer shape of alight emitting component which is based on a light emitting componentimage.

The present disclosure adopts the following means in order to achievethe above-described main object.

A first mounting device of the present disclosure is a mounting devicewhich mounts a light emitting component which includes an illuminantonto a board, including component holding means which is capable ofholding the light emitting component, moving means for causing thecomponent holding means to move, imaging means for imaging a regionwhich includes at least a portion of the illuminant in the lightemitting component to acquire a light emitting component image,illuminant coordinates detection means for detecting coordinates of aspecific part of the illuminant based on the light emitting componentimage, and control means for controlling the component holding means andthe moving means to perform mounting of the light emitting componentsuch that the light emitting component is held, the light emittingcomponent moves over the board, and the specific part of the illuminantis disposed at predetermined coordinates on the board based oncoordinates of the specific part which are detected, without using theinformation relating to an outer shape of the light emitting componentwhich is based on the light emitting component image.

In the first mounting device of the present disclosure, a region whichincludes at least a portion of the illuminant in the light emittingcomponent is imaged and the light emitting component image is acquiredwhen mounting the light emitting component which includes the illuminantonto the board. Next, the coordinates of the specific part of theilluminant are detected based on the light emitting component image. Thecomponent holding means and the moving means are controlled to performthe mounting of the light emitting component such that the lightemitting component is held, the light emitting component moves over theboard, and a specific part of the illuminant is positioned atpredetermined coordinates on the board based on the coordinates of thespecific part which are detected, without using information relating toan outer shape of the light emitting component which is based on thelight emitting component image. In this manner, the mounting isperformed using the coordinates of the specific part of the illuminantas a reference instead of the coordinates of the light emittingcomponent. Therefore, even if the position of the illuminant in thelight emitting component is deviated from the design value, it ispossible to accurately position the illuminant on the board. It ispossible to position the illuminant without using the informationrelating to the outer shape of the light emitting component which isbased on a light emitting component image. The light emitting componentmay be capable of being mounted such that the specific part of theilluminant is resultantly disposed at the predetermined coordinates onthe board, and it is not necessary to store the predeterminedcoordinates on the board in advance, to derive the predeterminedcoordinates on the board, or the like.

In the first mounting device of the present disclosure, the mountingdevice further includes positional relationship storage means forstoring a positional relationship between coordinates of the specificpart of the illuminant and holding coordinates at which the componentholding means holds the light emitting component, and mountingcoordinates storage means for storing mounting coordinates on the boardin the positional relationship with the predetermined coordinates on theboard, and the control means may derive actual holding coordinates whichare in the positional relationship with coordinates of the specific partbased on coordinates of the specific part which are detected and thepositional relationship, and may control the component holding means andthe moving means such that the light emitting component is held at theactual holding coordinates and a portion which is held is disposed atthe mounting coordinates. In the mounting device, the actual holdingcoordinates at which the light emitting component is held during themounting are determined using the coordinates of the specific part ofthe illuminant which are detected from the light emitting componentimage as a reference. Therefore, even if the position of the illuminantin the light emitting component is deviated from the design value, thepositional relationship between the specific part of the illuminant andthe portion which is held in the light emitting component is alwaysfixed. Accordingly, it is possible to accurately position the specificpart of the illuminant at predetermined coordinates on the board bysimply positioning the portion which is held at the mounting coordinateswhich are stored in advance.

In this case, the positional relationship may be a positionalrelationship between the specific part of the illuminant and a center ofthe light emitting component in a case in which a position of theilluminant in the light emitting component is according to the designvalue. By doing so, in a case in which the position of the illuminant inthe light emitting component is according to the design value, thecenter position of the light emitting component becomes the actualholding coordinates. In a case in which the position of the illuminantis deviated from the design value, a position which is deviated from thecenter position of the light emitting component by the amount becomesthe actual holding coordinates. In other words, a position whichcorresponds to the positional deviation of the illuminant using thecenter position of the light emitting component as a reference becomesthe actual holding coordinates. Therefore, in comparison to a case inwhich the actual holding coordinates are defined using the vicinity ofthe end portion of the light emitting component as a reference, forexample, the actual holding coordinates are deviated from the lightemitting component, and it becomes difficult for a state to arise inwhich the light emitting component may not be held.

In the first mounting device of the present disclosure, the controlmeans may derive a positional relationship between coordinates of thespecific part which are detected and predetermined holding coordinatesat which the component holding means holds the light emitting component,and may control the component holding means and the moving means suchthat the specific part of the illuminant is positioned at predeterminedcoordinates on the board based on the positional relationship. By doingso, since the positional relationship between the predetermined holdingcoordinates of the light emitting component and the coordinates of thespecific part of the detected illuminant is derived, and the mounting ofthe light emitting component is performed based on the positionalrelationship, it is possible to accurately position the specific part ofthe illuminant at predetermined coordinates on the board.

In the first mounting device of the present disclosure, the imagingmeans may be a mark camera which is capable of imaging a mark which ison the board. By doing so, since the mark camera also serves as theimaging means for imaging the light emitting component, it is possibleto reduce the number of components of the mounting device. In the markcamera, there is a case in which the visual field is narrow, and theilluminant and the outer shape portion of the light emitting componentmay not be imaged as a single image. In other words, there is a case inwhich an image, from which it is possible to acquire both thecoordinates of the specific part of the illuminant and informationrelating to the outer shape of the light emitting component, may not becaptured. Therefore, there is a great meaning to applying the presentdisclosure which does not use the information relating to the outershape of the light emitting component which is based on the lightemitting component image.

The second mounting device of the present disclosure is a mountingdevice which mounts a light emitting component which includes anilluminant onto a board, including component holding means which iscapable of holding the light emitting component, moving means forcausing the component holding means to move, imaging means for imaging aregion which includes at least a portion of the illuminant in the lightemitting component to acquire a light emitting component image,positional relationship storage means for storing a positionalrelationship between coordinates of a specific part of the illuminantand holding coordinates at which the component holding means holds thelight emitting component, illuminant coordinates detection means fordetecting coordinates of the specific part of the illuminant based onthe light emitting component image, and control means for derivingactual holding coordinates which are in the positional relationship withcoordinates of the specific part which are detected without usinginformation relating to an outer shape of the light emitting componentwhich is based on the light emitting component image and for controllingthe component holding means and the moving means to perform mounting ofthe light emitting component such that the light emitting component isheld at the actual holding coordinates and the portion which is held isdisposed at predetermined mounting coordinates.

In the second mounting device of the present disclosure, a region whichincludes at least a portion of the illuminant in the light emittingcomponent is imaged and the light emitting component image is acquiredwhen mounting the light emitting component which includes the illuminantonto the board. Next, the coordinates of the specific part of theilluminant are detected based on the light emitting component image.Next, the actual holding coordinates which are in the predeterminedpositional relationship with the coordinates of the specific part whichare detected is derived without using the information relating to theouter shape of the light emitting component which is based on a lightemitting component image. The component holding means and the movingmeans are controlled to perform the mounting of the light emittingcomponent such that the light emitting component is held at the actualholding coordinates and the portion which is held is disposed at thepredetermined mounting coordinates. In this manner, the actual holdingcoordinates at which the light emitting component is held during themounting are determined using the coordinates of the specific part ofthe illuminant which are detected from the light emitting componentimage as a reference. Therefore, even if the position of the illuminantin the light emitting component is deviated from the design value, thepositional relationship between the specific part of the illuminant andthe portion which is held in the light emitting component is alwaysfixed. Accordingly, by positioning the portion which is held at thepredetermined mounting coordinates, the specific part of the illuminantis always positioned at the coordinates which are in the predeterminedpositional relationship from the mounting coordinates. Therefore, evenif the position of the illuminant in the light emitting component isdeviated from the design value, it is possible to accurately positionthe illuminant on the board. It is possible to position the illuminantwithout using the information relating to the outer shape of the lightemitting component which is based on a light emitting component image.

In the second mounting device of the present disclosure, various aspectsof the first mounting device of the present disclosure which isdescribed above may be adopted. For example, the positional relationshipmay be a positional relationship between the specific part of theilluminant and a center of the light emitting component in a case inwhich a position of the illuminant in the light emitting component isaccording to the design value. The imaging means may be a mark camerawhich is capable of imaging a mark which is on the board.

The nozzle 40is lifted and lowered in the Z-axis direction (vertical direction) whichorthogonally intersect the X-axis and Y-axis directions by a holderlifting and lowering device which uses a Z-axis motor 45 as a drivingsource. The mounting head 24 sucks and holds the components using thenozzles 40; however, is not particularly limited thereto as long as itis possible to hold a component. For example, the mounting head 24 maybe provided with a mechanical chuck which grips and holds a component.

The mark camera 34 is a device which images the board 70 from above, andis installed on the lower surface of the X-axis slider 26. The markcamera 34 is a camera, below which is an imaging region, and which readsfiducial marks which are on the board 70 indicating a reference positionof the board 70, a reference position at which to dispose a component,or the like. The mark camera 34 moves in the X-Y directions togetherwith the movement of the mounting head 24.

The reel unit 56 is provided with a plurality of the reels 57, and isattached to be attachable and detachable to the front side of themounting device 11, and a tape in which the components are stored iswound onto the reel 57. The tape is unwound from the reel 57, and is fedout by a feeder section 58 at the collection position at whichcollection is performed by the mounting head 24. A plurality of thefeeder sections 58 are installed corresponding to the number of thereels 57 which may be attached to or detached from the mounting device11.

The parts camera 54 is disposed on the front of the supporting board 20of the front side of the conveyance section 18. The imaging range of theparts camera 54 is above the parts camera 54. When the nozzle 40 whichsucks the component passes over the parts camera 54, the parts camera 54images the state of the component which is sucked by the nozzle 40, andoutputs the image to the control device 60.

As illustrated in FIG. 1, the control device 60 is configured as amicroprocessor centered on a CPU 61, is provided with a ROM 62 whichstores process programs, a RAM 63 which is used as a working region, theHDD 64 which stores various data, an input and output interface 65 forperforming transactions of electrical signals with an external device,and the like, and these are electrically connected via a bus 66.

The management computer 80 is a PC which manages the informationrelating to the mounting process, and is provided with an input device87 such as a mouse and keyboard, a display 88, and the like. In an HDDwhich is not illustrated of the management computer 80, the productionjob data which includes the mounting information 67 which is describedlater is stored in an HDD which is not illustrated. In addition to themounting information 67, the production job data includes informationsuch as the information indicating how many of the board 70 to whichcomponents are to be mounted to manufacture, and the position of thefiducial marks of the board 70.

Next, description will be given of the operation of the mounting system10 of the present embodiment which is configured in this manner, inparticular, of the mounting process in which the mounting device 11mounts various components onto the board 70. FIG. 2 is a flowchartillustrating an example of a mounting process routine which is executedby the CPU 61 of the control device 60. This routine is stored on theHDD 64 of the mounting device 11 and is executed by a start instructionperformed by a worker. When the routine is started, the CPU 61 of thecontrol device 60 acquires the production job data which includes themounting information 67 from the management computer 80 and stores theproduction job data in the HDD 64 (step S100). The CPU 61 may receivethe production job data from the management computer 80 in advance andstore the production job data in the HDD 64.

FIG. 3 is an explanatory diagram of the mounting information 67 which isstored in the HDD 64. As illustrated, information in which the mountingorder, the component type, the mounting coordinates, the holdingcoordinates, and the like of the components to be mounted onto the board70 are associated is included in the mounting information 67. Themounting coordinates are coordinates (XY-coordinates) representing theposition on the board 70 at which to dispose the component. The holdingcoordinates are coordinates (XY-coordinates) representing the positionat which the component is sucked and held by. In the present embodiment,the holding coordinates are defined in advance as coordinates of thecenter (the center in the XY-direction) of the component.

Here, the light emitting component 75 is included in the componentswhich are defined to be mounted in the mounting information 67. In thepresent embodiment, a component A illustrated in FIG. 3 is the lightemitting component 75. FIG. 4 is an explanatory diagram illustratingvarious coordinates when mounting the light emitting component 75 ontothe board 70. As illustrated in the lower part of FIG. 4, the lightemitting component 75 is provided with a support board 76, and anilluminant 77 such as an LED which is attached onto the support board76. As illustrated in the lower part of FIG. 4, the center position ofthe light emitting component 75, that is, the center position (thecomponent center coordinates) of the support board 76 is the coordinates(C1, D1). For the light emitting component 75, the design position ofthe illuminant 77 in the light emitting component 75 is defined inadvance. As illustrated in the lower part of FIG. 4, the center position(the illuminant design center coordinates) of the illuminant 77 when theilluminant 77 is attached to the design position (when the illuminant 77is in the dashed line position) is the coordinates (A1, B1). The holdingcoordinates (C1, D1) are at a position which is deviated from theilluminant design center coordinates (A1, B1) in by a coordinate r inthe left direction and a coordinate s forward. To summarize, holdingcoordinates (C1, D1)=coordinates (A1−r, B1−s). In other words, therelative position of the holding coordinates in relation to theilluminant design center coordinates is the coordinates (−r, −s). Asillustrated in FIG. 3, the coordinates (C1, D1) are included in themounting information 67 as the holding coordinates corresponding to thecomponent A (the light emitting component 75). The coordinates (A1, B1)are included in the mounting information 67 as the illuminant designcenter coordinates corresponding to the component A (the light emittingcomponent 75). In this manner, the positional relationship between theilluminant design center coordinates which are the center of theilluminant 77 and the holding coordinates at which the mounting head 24holds the light emitting component 75 is included in the mountinginformation 67. The holding coordinates and the illuminant design centercoordinates are values which are defined for each type of the lightemitting component 75. Therefore, as illustrated in FIG. 3, the holdingcoordinates and the illuminant design center coordinates correspondingto the component A are the same values for both the mounting order 1 andthe mounting order 2. In the mounting information 67, the value of theilluminant design center coordinates is not associated with thecomponents other than the light emitting component 75 (components B to Gand the like).

In the present embodiment, the mounting coordinates are coordinateswhich use the fiducial marks of the board 70 as an origin point. Theholding coordinates and the illuminant design center coordinates arecoordinates which use the reference position which is stored in the HDD64 in advance for each of the plurality of feeder sections 58 as theorigin point. The holding coordinates and the illuminant design centercoordinates are defined as the coordinates of the component whichunwound from the reel 57 and is collected next by the mounting head 24(the component which is fed out by the feeder section 58 to thecollection position) among the plurality of components which are storedin the tape of the reel 57.

When the production job data which includes the mounting information 67is stored, the CPU 61 causes the board 70 to be conveyed (step S110). Inthis process, the CPU 61 causes the board 70 to be conveyed using theconveyor belt 22 and 22 of the conveyance section 18, and causes thecomponent to be fixed to the board 70 at a predetermined mountingposition at which a placement process is performed. Next, the CPU 61performs a process of detecting the position of the fiducial marks ofthe board 70 (step S120). In this process, the CPU 61 causes the markcamera 34 to move to the position of the board mark using the sliders 26and 30 based on the production job data. Next, the CPU 61 causes themark camera 34 to image the board mark. The CPU 61 detects the position(the XY-coordinates) of the fiducial marks based on the captured imageand stores the position in the RAM 63. The CPU 61 ascertains thecoordinates (for example, the mounting coordinates or the like) on theboard 70 in the following process, using the coordinates of the fiducialmarks which are detected as the origin point.

Next, the CPU 61 determines a component which is yet to be disposedaccording to the mounting order of the mounting information 67 to be asuction target (step S140). The CPU 61 determines whether or not thesuction target is the light emitting component 75 (step S150). The CPU61 performs the determination based on the component type of the suctiontarget in the mounting information 67, for example. The CPU 61 mayperform the determination according to whether or not the illuminantdesign center coordinates are associated with the component which is thesuction target in the mounting information 67.

When the suction target is the light emitting component 75 in step S150,the CPU 61 causes the mark camera 34 to image the illuminant 77 of thelight emitting component 75 to acquire a light emitting component image(step S160). In this process, the CPU 61 first acquires the illuminantdesign center coordinates of the suction target which is defined in themounting information 67 from the HDD 64. The CPU 61 causes the markcamera 34 to move such that the center of an imaging range 35 (refer tothe lower part of FIG. 4) of the mark camera 34 is positioned at theilluminant design center coordinates corresponding to the feeder section58 which feeds out the suction target. The CPU 61 acquires the lightemitting component image using the mark camera 34. As illustrated inFIG. 4, the visual field, that is, the imaging range 35 of the markcamera 34 is defined in advance such that it is possible to image theentirety of the illuminant 77. The imaging range 35 is empiricallydefined in advance such that it is possible to image the entirety of theilluminant 77 even if the position of the illuminant 77 in the lightemitting component 75 is deviated from the design value. In the presentembodiment, the imaging range 35 does not have enough width to enablethe imaging of the entirety of the illuminant 77 and the outer shapeportion of the light emitting component 75 (for example, the endportions, corner portions, and the like of any of the front, rear, left,and right of the support board 76, for example) as a single image.

Next, the CPU 61 detects the actual coordinates (illuminant detectedcenter coordinates) of the center of the illuminant 77 based on theacquired light emitting component image (step S170). In this process,the CPU 61 first compares the light emitting component image with acomparison image which is obtained by imaging the light emittingcomponent 75 centered on the illuminant 77 in advance. The CPU 61detects the region of the illuminant 77 in the light emitting componentimage based on the comparison results, and detects the illuminantdetected center coordinates based on the center position of the detectedregion. Accordingly, for example, in a case in which the position of theilluminant 77 in the light emitting component 75 is according to thedesign value, the CPU 61 detects the same coordinates as the illuminantdesign center coordinates (A1, B1) as the illuminant detectedcoordinates. Meanwhile, in a case in which the position of theilluminant 77 in the light emitting component 75 is deviated in the leftdirection by the coordinate a and to the front by the coordinate b fromthe design value as illustrated in the lower part of FIG. 4, the CPU 61detects the coordinates (A2, B2)=coordinates (A1−a, B1−b) as theilluminant detected coordinates. The comparison image may be included inthe production job data, and may be stored in advance in the HDD 64. Theembodiment is not limited to a case in which the comparison image isused, and reference information for the CPU 61 to detect the illuminantdetected center coordinates based on the light emitting component imagemay be present. For example, a threshold for distinguishing a colordifference between the pixels of the illuminant 77 and the pixels of thesupport board 76 in the light emitting component image may be includedin the production job data as reference information.

Next, the CPU 61 derives the actual holding coordinates which are theposition at which the light emitting component 75 is actually suckedbased on the illuminant detected center coordinates which are detectedand the holding coordinates and the illuminant design center coordinateswhich are included in the mounting information 67 (step S180). In thisprocess, the CPU 61 first derives a deviation amount (the differencebetween both coordinates) in the XY-directions from the illuminantdesign center coordinates to the illuminant detected center coordinates.Next, the CPU 61 derives the coordinates which are deviated from theholding coordinates by the deviation amount as the actual holdingcoordinates. For example, in a case in which the position of theilluminant 77 in the light emitting component 75 is according to thedesign value, the illuminant design center coordinates and theilluminant detected center coordinates are the same, and the deviationamount becomes (0, 0). Therefore, the CPU 61 derives the samecoordinates as the holding coordinates which are included in themounting information 67 as the actual holding coordinates. Meanwhile, ina case in which the position of the illuminant 77 in the light emittingcomponent 75 is deviated from the design value as illustrated in thelower part of FIG. 4, the deviation amount from the illuminant designcenter coordinates (A1, B1) to the illuminant detected centercoordinates (A2, B2) becomes (−a, −b). Therefore, the CPU 61 derivescoordinates (C2, D2)=(C1−a, D1−b), which are deviated by the deviationamount (−a, −b) from the holding coordinates (C1, D1) which are includedin the mounting information 67, as the actual holding coordinates. Ascan be understood from FIG. 4, the actual holding coordinates (C2, D2)are coordinates (A2−r, B2−s) which are deviated in the left direction bya coordinate r, and to the front by a coordinate s from the illuminantdetected center coordinates (A2, B2). Accordingly, as can be understoodfrom FIG. 4, the positional relationship between the illuminant detectedcenter coordinates (A2, B2) and the actual holding coordinates (C2, D2)in a case in which the position of the illuminant 77 is deviated fromthe design value is the same as the positional relationship between theilluminant design center coordinates (A1, B1) and the holdingcoordinates (C1, D1) in a case in which the position of the illuminant77 is according to the design value. In other words, the positionalrelationship between the illuminant detected center coordinates (A2, B2)and the actual holding coordinates (C2, D2) is not influenced by thedeviation amount (−a, −b) from the illuminant design center coordinates(A1, B1) to the illuminant detected center coordinates (A2, B2). In thismanner, the CPU 61 derives the actual holding coordinates such that thepositional relationship between the illuminant detected centercoordinates and the actual holding coordinates is always the sameregardless of the deviation amount of the position of the illuminant 77from the design value. The CPU 61 causes the mounting head 24 to movesuch that the tip of the nozzle 40 is positioned at the actual holdingcoordinates, and the light emitting component 75 is sucked and held byat the actual holding coordinates (step S190). In this manner, when theCPU 61 causes the mounting head 24 to hold the light emitting component75, the CPU 61 causes the mounting head 24 to hold the light emittingcomponent 75 at the actual holding coordinates which are derived basedon the illuminant detected center coordinates instead of at the holdingcoordinates which are specified in the mounting information 67.Meanwhile, when the suction target is not the light emitting component75 in step S150, the CPU 61 causes the mounting head 24 to move suchthat the tip of the nozzle 40 is positioned at the holding coordinateswhich is specified by the mounting information 67, and sucks and holdsthe component which is the suction target at the holding coordinates(step S200).

When the suction target is sucked in step S190 or step S200, the CPU 61determines whether or not the number of components which are sucked bythe mounting head 24 is less than the number (12) of the nozzles 40 ofthe nozzle holding body 42 (step S210). When the number of suckedcomponents is less than the number of the nozzles 40 of the nozzleholding body 42 in step S210, the CPU 61 performs the processes of stepS140 onward. In other words, the CPU 61 sequentially sets the suctiontarget, if the suction target is the light emitting component 75, causesthe component to be sucked at the actual holding coordinates using thenozzle 40, and if the suction target is a component other than the lightemitting component 75, causes the component to be sucked at the holdingcoordinates using the nozzle 40. In step S210, when the number of suckedcomponents is not less than the number of nozzles 40 of the nozzleholding body 42, that is, when all 12 of the nozzles 40 of the nozzleholding body 42 suck and hold the components, the CPU 61 acquires theholding state of the components which are held by the nozzles 40 (stepS220). In this process, the CPU 61 causes the mounting head 24 to moveto the top portion of the parts camera 54, and acquires an image whichis captured by the parts camera 54. The CPU 61 analyzes the image anddetermines the presence or absence of abnormalities in the components,abnormalities relating to the posture of the inclination or the like ofthe component, deviation in the holding position, and the like. The CPU61 causes components which have abnormalities to be discarded. In thepresent embodiment, the CPU 61 omits the determination of the presenceor absence of abnormalities for the light emitting components 75. Whenall of the components which are held by the nozzle 40 of the nozzleholding body 42 are the light emitting components 75, the CPU 61 doesnot perform the imaging using the parts camera 54 and omits the processitself of step S220. However, the CPU 61 may not perform the omission.

Next, the CPU 61 causes the component which is held by the mounting head24 to be disposed (mounted) at the mounting coordinates on the board 70(step S230). In this process, the CPU 61 causes the mounting head 24 tomove to ensure that the tip of the nozzle 40 which is holding thecomponent is positioned at the mounting coordinates, and causes theZ-axis motor 45 to lower the component to dispose the component at themounting coordinates. In other words, the CPU 61 performs movement anddisposition of the component onto the board 70 such that the portionwhich holds the component is disposed at the mounting coordinates. TheCPU 61 causes the plurality of components which are held by the mountinghead 24 to be sequentially disposed at the mounting coordinatesaccording to the mounting order of the mounting information 67.

Here, description will be given of a case in which the light emittingcomponent 75 is disposed at the mounting coordinates using FIG. 4. Asdescribed above, even if the position of the illuminant 77 in the lightemitting component is deviated from the design value, the positionalrelationship between the actual holding coordinates and the illuminantdetected center coordinates of the light emitting component 75 is thesame. Therefore, as illustrated in FIG. 4, when the CPU 61 disposes theportion which holds the light emitting component 75 (the portioncorresponding to the actual holding coordinates (C2, D2) during thesuction) at the mounting coordinates (G, H), the center of theilluminant 77 is positioned at predetermined coordinates (E,F)=coordinates (G+r, H+s). In this manner, in the present embodiment,due to the CPU 61 holding the light emitting component 75 at the actualholding coordinates and disposing the light emitting component 75 at themounting coordinates, the center of the illuminant 77 is disposed at thepredetermined coordinates regardless of the positional deviation fromthe design value of the illuminant 77. The predetermined coordinates area predetermined position on the board 70 at which the center of theilluminant 77 is to be disposed. In other words, the mountingcoordinates which are included in the mounting information 67 aredefined in advance by performing an inverse operation from thepredetermined coordinates as coordinates at which the positionalrelationship between the predetermined coordinates and the mountingcoordinates becomes the same as the positional relationship between theilluminant design center coordinates and the holding coordinates. Theposition of the support board 76 in the light emitting component 75changes according to the positional deviation from the design value ofthe illuminant 77 in the light emitting component 75. In the upper partof FIG. 4, the position of the support board 76 on the board 70 afterthe mounting in a case in which the position of the illuminant 77 isaccording to the design value is illustrated using a dashed line. Theposition of the support board 76 on the board 70 after the mounting in acase in which the illuminant detected center coordinates of theilluminant 77 are the coordinates (A2, B2) is illustrated using a solidline.

In step S230, when all of the components which are held by the mountinghead 24 are disposed on the board 70, the CPU 61 determines whether ornot there is currently a component which is yet to be disposed on theboard 70 based on the mounting information 67 (step S240), and executesthe processes of step S130 onward when there is a component which is yetto be mounted. In other words, the CPU 61 causes the nozzle 40 to bechanged as necessary, and if the suction target is the light emittingcomponent 75, holds the suction target at the actual holdingcoordinates, and if the suction target is a component other than thelight emitting component 75, holds the suction target at the holdingcoordinates, and disposes the component which is held at the mountingcoordinates. Meanwhile, when there is currently no component which isyet to be disposed on the board 70, the CPU 61 causes the current board70 for which the mounting is completed to be discharged (step S250), anddetermines whether or not the production is completed based on thenumber of boards for which the mounting is completed (step S260). Whenthe production is not completed, the CPU 61 repeatedly executes theprocesses of step S110 onward. Meanwhile, when the production iscompleted, the CPU 61 ends the routine.

Here, the correspondence between the constituent elements of the presentembodiment and the constituent elements of the present disclosure willbe rendered clear. The mounting head 24 of the present embodimentcorresponds to the component holding means of the present disclosure,the X-axis slider 26 and the Y-axis slider 30 correspond to the movingmeans, the mark camera 34 corresponds to the imaging means, and the CPU61 corresponds to the illuminant coordinates detection means and thecontrol means. The HDD 64 corresponds to the positional relationshipstorage means and the mounting coordinates storage means.

According to the mounting system 10 which is described above, the CPU 61causes a region which includes at least a portion of the illuminant 77of the light emitting component 75 to be imaged and acquires the lightemitting component image when mounting the light emitting component 75which includes the illuminant 77 onto the board 70. Next, the CPU 61detects the coordinates (the illuminant detected center coordinates) ofthe specific part (the center) of the illuminant 77 based on the lightemitting component image. The CPU 61 controls the mounting head 24, theX-axis slider 26, and the Y-axis slider 30 to mount the light emittingcomponent 75 such that the light emitting component 75 is held, thelight emitting component 75 is moved to above the board 70, and thecenter of the illuminant 77 is positioned at predetermined coordinateson the board 70 based on the illuminant detected center coordinates,without using the information relating to the outer shape of the lightemitting component 75 which is based on the light emitting componentimage. In this manner, the CPU 61 performs the mounting using theilluminant detected center coordinates as a reference instead of thecoordinates of the light emitting component 75. Therefore, even if theposition of the illuminant 77 in the light emitting component 75 isdeviated from the design value, it is possible to accurately positionthe illuminant 77 on the board 70. It is possible to position theilluminant 77 without using the information relating to the outer shapeof the light emitting component 75 which is based on a light emittingcomponent image. After mounting the light emitting component 75 onto theboard 70, there is a case in which a lens component or the like isplaced over the illuminant 77. At this time, there is a case in whichwhen the positional relationship between the lens component and theilluminant 77 is deviated, the desired luminance may not be obtained.There is a case in which it may not be possible to change the positionof the lens component on the board 70 according to the position of theilluminant 77 such as a case in which a portion of the lens component isinserted into a hole which is opened in the board 70 and the lenscomponent is fixed. Even this case, in the mounting device 11, itbecomes easier to obtain the desired luminance in order for the CPU 61to accurately position the center of the illuminant 77 at predeterminedcoordinates regardless of the positional deviation of the illuminant 77in the light emitting component 75. In the explanation which uses FIG.4, a case is exemplified in which the position of the illuminant 77 inthe light emitting component 75 is deviated from the design value;however, even in a case in which the position of the entirety of thelight emitting component 75 which is collected by the mounting head 24is deviated, it is possible to accurately position the illuminant 77 onthe board 70 in the same manner due to the CPU 61 performing the processdescribed above. In other words, in the embodiment described above, theCPU 61 performs the mounting using the illuminant detected centercoordinates as a reference instead of the coordinates of the lightemitting component 75, and thus, it is possible to accurately positionthe illuminant 77 on the board 70 without particularly distinguishingwhich of positional deviation of the illuminant 77 caused by positionaldeviation of the entirety of the light emitting component 75 andpositional deviation of the illuminant 77 in the light emittingcomponent 75 is occurring. Even in a case in which both the positionaldeviation of the entirety of the light emitting component 75 and thepositional deviation of the illuminant 77 in the light emittingcomponent 75 are occurring, it is possible for the CPU 61 to accuratelyposition the illuminant 77 on the board 70 in the same manner. Examplesof cases in which the position of the entirety of the light emittingcomponent 75 is deviated include a case in which the position of thelight emitting component 75 in the tape is deviated, for example, and acase in which deviation occurs in the tape feeding by the feeder section58.

The mounting information 67 which includes the mounting coordinates onthe board 70 which is in the same positional relationship as thepositional relationship between the illuminant design center coordinatesand the holding coordinates of the illuminant 77, or the positionalrelationship between the illuminant design center coordinates and theholding coordinates in relation to the predetermined coordinates on theboard 70 is stored in the HDD 64. The CPU 61 derives the actual holdingcoordinates which are in the same positional relationship in relation tothe illuminant detected center coordinates based on the illuminantdetected center coordinates and the positional relationship which isstored, causes the light emitting component 75 to be held at the actualholding coordinates, and disposes the held portion at the mountingcoordinates. In this manner, the CPU 61 defines the actual holdingcoordinates using the illuminant detected center coordinates as areference. Therefore, even if the position of the illuminant 77 in thelight emitting component 75 is deviated from the design value, thepositional relationship between the center of the illuminant 77 and theportion which is held in the light emitting component 75 is alwaysfixed. Accordingly, the CPU 61 is capable of accurately positioning thecenter of the illuminant 77 at predetermined coordinates on the board 70by simply positioning the portion of the light emitting component 75which is held by the mounting head 24 at the mounting coordinates whichare stored in advance.

The positional relationship which is stored in the HDD 64 is thepositional relationship between the illuminant design center coordinatesand the holding coordinates. Therefore, in a case in which the positionof the illuminant 77 in the light emitting component 75 is according tothe design value, the center position of the light emitting component 75becomes the actual holding coordinates. In a case in which the positionof the illuminant 77 is deviated from the design value, a position whichis deviated from the center position of the light emitting component 75by the amount becomes the actual holding coordinates. In other words, aposition which corresponds to the positional deviation of the illuminant77 using the center position of the light emitting component 75 as areference becomes the actual holding coordinates. Therefore, incomparison to a case in which the actual holding coordinates are definedusing the vicinity of the end portion of the light emitting component 75as a reference (the holding coordinates), for example, the actualholding coordinates are deviated from the light emitting component 75,and it becomes difficult for a state to arise in which the lightemitting component 75 may not be held.

Since the mark camera 34 also serves as the imaging means for imagingthe light emitting component 75, it is possible to reduce the number ofcomponents of the mounting device 11. In the mark camera 34, there is acase in which the visual field is narrow, and the illuminant 77 and theouter shape portion of the light emitting component 75 may not be imagedas a single image. In other words, there is a case in which an image,from which it is possible to acquire both the illuminant detected centercoordinates and information relating to the outer shape of the lightemitting component 75, may not be captured. Therefore, there is a greatmeaning to applying the present disclosure which does not use theinformation relating to the outer shape of the light emitting component75 which is based on the light emitting component image.

It goes without saying that the present disclosure is not limited in anymanner by the embodiment described above, and may be carried out in anyof various modes which fall within the technical scope of the presentdisclosure.

For example, in the embodiment described above, the CPU derives theactual holding coordinates based on the illuminant detected centercoordinates, holds the light emitting component 75 at the actual holdingcoordinates, and disposes the portion which is held at the mountingcoordinates; however, the configuration is not limited thereto. Themounting device 11 may perform the mounting such that the center of thelight emitting component 75 is disposed at predetermined coordinates onthe board 70 based on the illuminant detected center coordinates whichare detected from the illuminant image. For example, the CPU 61 maycontrol the mounting head 24 to hold the light emitting component 75 atthe holding coordinates without deriving the actual holding coordinatesregardless of the illuminant detected center coordinates, and may derivethe mounting coordinates based on the illuminant detected centercoordinates. FIG. 5 is a flowchart illustrating an example of a mountingprocess routine of the alternative embodiment. The routine is the sameas the mounting process routine of FIG. 2 except for in that steps S175a to S190 a are performed instead of steps S180 to S190 which aredescribed above. In a case in which the mounting process routine of thealternative embodiment is performed, the predetermined coordinates(desired coordinates on the board 70 at which the center of theilluminant 77 is to be disposed) described above are associated with thelight emitting component 75 instead of the mounting coordinates in themounting information 67 which is stored in the HDD 64 in step S100. Inthe mounting process routine of the alternative embodiment, the CPU 61detects the illuminant detected center coordinates based on the lightemitting component image in step S170, and subsequently derives thepositional relationship between the illuminant detected centercoordinates and the holding coordinates which are associated with thelight emitting component 75 which is the suction target in the mountinginformation 67 (step S175 a). Description will be given of thepositional relationship which is derived by the CPU 61 using FIG. 6. Forexample, in a case in which the position of the illuminant 77 in thelight emitting component 75 is according to the design value, the CPU 61derives the relative coordinates (−r, −s) of the holding coordinates(C1, D1) which use the illuminant detected center coordinates (=theilluminant design center coordinates) (A1, B1) as a reference (an originpoint) as the positional relationship between the illuminant detectedcenter coordinates and the holding coordinates. Meanwhile, in a case inwhich the position of the illuminant 77 in the light emitting component75 is at coordinates (A2, B2) which are deviated from the design valueas illustrated in the lower part of FIG. 6, the CPU 61 derives therelative coordinates (−c, −d)=the relative coordinates (−r+a, −s+b) ofthe holding coordinates (C1, D1) which use the illuminant detectedcenter coordinates (A2, B2) as an origin point as the positionalrelationship between the illuminant detected center coordinates and theholding coordinates. In this manner, a positional relationship whichcorresponds to the illuminant detected center coordinates is derived.Next, the CPU 61 derives the mounting coordinates based on thepositional relationship which is derived and the predeterminedcoordinates which are stored in the mounting information 67 (step S180a). The CPU 61 derives the mounting coordinates such that the positionof the mounting coordinates which use the predetermined coordinates as areference becomes the same as the position of the holding coordinateswhich use the illuminant detected center coordinates as a reference. Forexample, in FIG. 6, in a case in which the position of the illuminant 77in the light emitting component 75 is according to the design value, theCPU 61 derives the coordinates (G, H)=the coordinates (E−r, F−s) whichare in the position of the relative coordinates (−r, −s), which use thepredetermined coordinates (E, F) as a reference, as the mountingcoordinates. Meanwhile, in FIG. 6, in a case in which the illuminantdetected center coordinates are the coordinates (A2, B2), the CPU 61derives the coordinates (I, J)=the coordinates (E−c, F−d) which are inthe position of the relative coordinates (−c, −d), which use thepredetermined coordinates (E, F) as a reference, as the mountingcoordinates. The CPU 61 causes the mounting head 24 to move, suck andhold the light emitting component 75 at the holding coordinates (stepS190 a), and performs the processes of step S210 onward. After stepS220, the CPU 61 disposes (mounts) the component which is held by themounting head 24 at the mounting coordinates on the board 70 (stepS230). In this manner, in the mounting device 11 of the alternativeembodiment, the CPU 61 derives the mounting coordinates as thecoordinates of the movement destination of the light emitting component75 which is held at the holding coordinates at which it is possible todispose the illuminant detected center coordinates at the predeterminedcoordinates based on the positional relationship between the illuminantdetected center coordinates and the holding coordinates. Accordingly,even if the position of the illuminant 77 in the light emittingcomponent 75 is deviated from the design value, it is possible toaccurately position the center of the illuminant 77 at the predeterminedcoordinates (E, F) on the board 70. In the mounting device 11 of thealternative embodiment, the illuminant design center coordinates whichare included in the mounting information 67 are merely the coordinateswhich indicate the imaging position when imaging the light emittingcomponent 75 in step S160. Therefore, even in a case in which theilluminant detected center coordinates are detected from the lightemitting component image, other coordinates may be included in themounting information 67 instead of the illuminant design centercoordinates. In the mounting device 11 of the alternative embodimentwhich is described above, the predetermined coordinates are included inthe mounting information 67; however, the configuration is not limitedthereto. For example, in a case in which, instead of the predeterminedcoordinates, the position of the illuminant 77 in the light emittingcomponent 75 is according to the design value, the mounting coordinatesand the positional relationship (the positional relationship between theilluminant design center coordinates and the holding coordinates) may beincluded in the mounting information 67. In this case, the CPU 61 mayderive the deviation amount between the positional relationship which isderived in step S175 a and the positional relationship which is includedin the mounting information 67, and may derive post-correction mountingcoordinates, which serve as coordinates which are obtained by deviatingthe mounting coordinates which are included in the mounting information67 by the deviation amount which is derived, in step S180 a. In stepS230, the CPU 61 may dispose (mount) the light emitting component 75which is held by the mounting head 24 at the post-correction mountingcoordinates on the board 70. Even in this case, it is possible toaccurately position the center of the illuminant 77 at the predeterminedcoordinates (E, F) on the board 70.

In the embodiment which is described above, the illuminant design centercoordinates and the holding coordinates are included in the mountinginformation 67 as the positional relationship between the illuminantdesign center coordinates and the holding coordinates of the illuminant77; however, as long as the information represents the positionalrelationship between the two, the configuration is not limited thereto.For example, relative coordinates which represent the position of theother coordinates when the coordinates of one of the illuminant designcenter coordinates and the holding coordinates are used as a referencemay be included in the mounting information 67 as the information whichrepresents the positional relationship. Even in this case, the CPU 61 iscapable of deriving the actual holding coordinates based on thepositional relationship between the illuminant detected centercoordinates and the mounting information 67.

In the embodiment described above, the CPU 61 detects the illuminantdetected center coordinates which are the center coordinates of theilluminant 77 based on the light emitting component image; however, theconfiguration is not limited thereto, and the CPU 61 may detect thecoordinates of a specific part of the illuminant 77. For example, theCPU 61 may detect the coordinates of the end portion, the cornerportion, or the like of one of the front, back, left, and right of theilluminant 77. Alternatively, the CPU 61 may detect the coordinates of apredetermined mark or the like which is arranged on the illuminant 77.The light emitting component image is an image which includes theentirety of the illuminant 77; however, the configuration is not limitedthereto. The imaging range 35 may be defined such that a region which isnecessary for detecting the coordinates of the specific part of theilluminant 77 is included in the light emitting component image. The CPU61 may detect the coordinates of a plurality of specific parts of theilluminant 77 such as detecting the coordinates of the center and thecoordinates of a corner portion of the illuminant 77.

In the embodiment described above, in step S180, the CPU 61 derivescoordinates which are deviated from the holding coordinates by thedeviation amount in the XY-directions from the illuminant design centercoordinates to the illuminant detected center coordinates as the actualholding coordinates. In other words, the CPU 61 derives the actualholding coordinates in consideration of the XY-directional deviation ofthe illuminant 77. At this time, the CPU 61 may derive the actualholding coordinates also in consideration of the inclination (rotationaldirection deviation) in the XY-plane of the illuminant 77. For example,the mounting device 11 may store the mounting information 67 whichincludes the positional relationships between the coordinates ofplurality of specific parts of the illuminant 77 and the holdingcoordinates, and the mounting coordinates on the board 70 which is inthe same positional relationship as the positional relationship betweenthe coordinates of the plurality of specific parts and the holdingcoordinates in relation to a plurality of predetermined coordinates onthe board 70 in the HDD 64. The CPU 61 may derive the actual holdingcoordinates which are in the same positional relationship as thepositional relationship which is stored in relation to the coordinatesof a plurality of specific parts which are detected based on thecoordinates of a plurality of specific parts which are detected from thelight emitting component image and the positional relationship which isstored, and may hold the light emitting component 75 at the actualholding coordinates and control the mounting head 24, the X-axis slider26, and the Y-axis slider 30 such that the held portion is disposed atthe mounting coordinates. Specifically, in steps S100, S170, and S180 ofthe embodiment which is described above, for example, the CPU 61 mayperform the following processes. In step S100, the CPU 61 acquires theproduction job data which includes the mounting information 67 whichincludes the coordinates (for example, the coordinates of the center ofthe illuminant 77 and the coordinates of the front left corner portionof the illuminant 77 of a case in which the position of the illuminant77 is according to the design value) of the plurality of specific partsof the illuminant 77, the holding coordinates, and the mountingcoordinates, and stores the production job data in the HDD 64. In stepS170, the CPU 61 detects the coordinates of the plurality of specificparts (for example, the center and the front left corner portion) withinthe illuminant 77 based on the light emitting component image. The CPU61 derives the deviation amount (the rotational angle) of the rotationaldirection of the illuminant 77 which is compares to a case in which theposition of the illuminant 77 is according to the design value based onthe coordinates of the plurality of specific parts which are detected,and the coordinates of the plurality of specific parts which are storedin the HDD 64. For example, the CPU 61 derives an angle formed by asegment of a line which joins the coordinates of the plurality ofspecific parts which are stored in the HDD 64 and a segment of a linewhich joins the coordinates of the plurality of specific parts which aredetected as the deviation amount of the rotational direction. Next, instep S180 the CPU 61 derives the actual holding coordinates which are inthe same positional relationship as the positional relationship which isstored in the HDD 64 in relation to the coordinates of the plurality ofspecific parts which are detected. In other words, the actual holdingcoordinates are derived as coordinates at which the positionalrelationship between the coordinates of the plurality of specific partswhich are stored in the HDD 64 and the holding coordinates, becomes thesame as the positional relationship between the coordinates of theplurality of specific parts which are detected and the actual holdingcoordinates. The CPU 61 causes the light emitting component 75 to besucked and held at the actual holding coordinates in step S190, anddisposes (mounts) the light emitting component 75 at the mountingcoordinates on the board 70 in step S230. At this time, the CPU 61causes the light emitting component 75 to be disposed (mounted) at themounting coordinates on the board 70 after rotating the light emittingcomponent 75 by the deviation amount of the rotational direction so asto correct the deviation amount of the rotational direction which isderived in step S170. By doing so, even in a case in which theilluminant 77 is deviated in the rotational direction in addition to acase in which the illuminant 77 is deviated in the XY-directions, theCPU 91 is capable of accurately positioning the illuminant 77 on theboard 70 also including the inclination (the positioning angle) of theilluminant 77. Even in the mounting process routine of the alternativeembodiment which is illustrated in FIG. 5, by using the coordinates ofthe plurality of specific parts of the illuminant 77, it is possible toaccurately position the illuminant 77 on the board 70 also inconsideration of the deviation in the rotational direction of theilluminant 77 in the same manner. Specifically, after detecting thecoordinates (for example, the coordinates of the center and the frontleft corner portion) of the plurality of specific parts of theilluminant 77 based on the light emitting component image in step S170,the CPU 61 derives the positional relationship between the coordinateswhich are detected and the holding coordinates which are associated withthe light emitting component 75 which is the suction target in themounting information 67 in step S175 a. In step S180 a, the CPU 61derives the mounting coordinates based on the positional relationshipwhich is derived and the plurality of predetermined coordinates (forexample, the desired coordinates on the board 70 at which the center andthe front left corner portion of the illuminant 77 are to be disposed)which are stored in advance as the mounting information 67. In otherwords, the CPU 61 derives the mounting coordinates such that theposition of the mounting coordinates which use the plurality ofpredetermined coordinates as a reference becomes the same as theposition of the holding coordinates which use the coordinates of theplurality of specific parts which are detected as a reference. The CPU61 derives an angle formed by a segment of a line which joins theplurality of predetermined coordinates which are stored in the HDD 64and a segment of a line which joins the coordinates of the plurality ofspecific parts which are detected as the deviation amount of therotational direction of the illuminant 77. The CPU 61 causes the lightemitting component 75 to be sucked and held at the actual holdingcoordinates in step S190 a, and disposes (mounts) the light emittingcomponent 75 at the mounting coordinates on the board 70 in step S230.At this time, the CPU 61 causes the light emitting component 75 to bedisposed (mounted) at the mounting coordinates on the board 70 afterrotating the light emitting component 75 by the deviation amount of therotational direction so as to correct the deviation amount of therotational direction which is derived in step S180 a.

In the embodiment described above, the imaging range 35 does not haveenough width to enable the imaging of the entirety of the illuminant 77and the outer shape portion of the light emitting component 75 as asingle image; however, the configuration is not limited thereto. In themounting device 11, the mark camera 34 also functions as the imagingmeans for imaging the light emitting component however, theconfiguration is not limited thereto, and a separate imaging means fromthe mark camera 34 may image the light emitting component image.

In the embodiment described above, the holding coordinates which areincluded in the mounting information 67 are set to the coordinates ofthe center of the light emitting component 75; however, theconfiguration is not limited thereto, and the coordinates of any portionin the light emitting component 75 may be used. However, since a statein which the actual holding coordinates become separated from the lightemitting component 75 and the light emitting component 75 may not beheld does not occur easily, it is preferable to use the coordinates ofthe center of the light emitting component 75 as the holdingcoordinates.

In the embodiment described above, the mounting coordinates arecoordinates which use the fiducial marks of the board 70 as an originpoint, and the holding coordinates and the illuminant design centercoordinates are coordinates which use the reference position which isstored in the HDD 64 in advance corresponding to each of the pluralityof feeder sections 58 as the origin point; however, the configuration isnot limited thereto, and other origin points may be used.
